SPECIFICATION forming part of Letters Patent No. 716,292, dated December16, 1902.

Application filed March 10, 1902. Serial M91423. on. model.)

have invented certain new and useful Im provements in Windmill-OilingApparatus,

of which the followingis a specification.

The objects of my invention are to provide a device capable of beingapplied in the way of an attachment to any ordinary windmill,

to which it is firmly secured in such a manner that it will not in anyway interfere with the usual functions of the windmill proper, and whenapplied to the windmill the operator may, by manipulating a pumpattached to the windmill-base,-supply lubricating-oil to all of theoperative parts of the windmill at the top of the tower, and when asufficient amount of oil has been supplied to the various bearings theoil in the supply-pipe will all return to the pump at the base of theWindmill, so that there will be no leakage or waste of the oil and sothat no oil will be left in the oil-supply pipes to harden under variousatmospheric conditions or clog the supply-pipes.

My invention consists in certain details in the construction,arrangement, and combination with a windmill of the various parts. ofthe attachment whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claims, andillustrated in the accompanying drawings, in which- Figure 1 shows inperspective the upper and lower portions of the windmill-tower with myinvention applied thereto as required in practical use. Fig. 2 shows anenlarged detail sectional View through a portion of the annular collarand connected parts at the top of the windmill-tower.

Referring to the accompanying drawings, I have used thereference-numeral 10 to indicate a corner-post of the windmill-tower;11, the platformat the base thereof. At the top of the windmill-tower isa metal cap 12, such as is usually provided to cover the tops of thecorner-post of awindmill-tower. Mounted on this cap 12 is an annularmetal collar 13, made of two parts, which divides the collar into twosemicircular pieces, which pieces are connected by the bolts 14. The topsurface of this collar is flat, and a series of bolts 15 are passedthrough the collar to engage the cap 12, so that the collar is firmlyfixed thereby to said cap, and the collar stands normally in ahorizontal position. The cap of the windmill-tower is usually smallestat its top, and hence a collar such as 13 will fit upon caps such as 12of the various sizes because it does not matter how near the top thecollar rests.

Bolted to the inner periphery of the collar 13 is a series of fiat metalguides 16, their upper ends projecting some distance above the collar13, each end being pointed at right angles and slotted to admit asliding bar 17. In the top of each of the bars 17 is a bolt 18, and aroller 19 is rotatably mounted on said bolt. At the bottom of each ofthe bars 17 is a wire 20. gle wire 21, which is attached to the lever22, fulcrumed to the base of the windmill-tower, and the hook 23 pivotedto said base is designed to engage the lever 22 to lock it atitsdownward limit of movement. Obviously when the lever 22 is presseddownwardly all of the rollers 19 will be forced downwardly at the sametime.

The reference-numeral 24 indicates a twopart annular metal ring, theparts of which are connected by means of the bolts 25, and said ring issubstantially the same size as the collar 13. On its under surface is anannular groove 26, and the ring 24 rests upon a flexible cushion orwasher 27, which. washer or cushion rests upon the top of the collar 13.The said guides 16 engage the inner surface of the ring 24, and therollers 19' engage itstop surface. Hence all movements of the ring 24,except rotatorymovements, are prevented. Fixed to the ring 24 is a pipe28, having communication with the annular chamber 26 and projectingupwardly and provided with a number of oil feeding pipes 29. Thesaidpipes 29 may be connected with the various oil-holes of a windmill-wheeland turntable. In this connection it is to be remembered that becausethe various makes of windmills are provided with oil-holes at differentpoints hence the pipes 29 are preferably flexible, so that they can beconnected direct These wires connect with a sin with the variousoil-holes of the Ordinary windmills, and the feeding-pipe 28 willobviously rotate with the wind-wheel upon the turn-table thereof, therollers 19 providing this movement.

Fixed to a portion of the windmill-tower near its base is a pump 30,having a handle 31 fulcrumed to the support 32,and connected with thepump-rod'33, fixed to the bottom of the pump, is a pipe 34, whichextends through the collar 13 and through the washer 27 to discharge itscontents into the annular chamber 26.

g In practical use the device is attached to a windmill as follows: Theparts 13 and 24: are divided and placed on opposite sides of thewindmill-tower and then the parts of each are bolted together, with thewasher 27 between them. Then the collar 13 is bolted to the top of thewindmill-tower, as described, and the supply-pipe 34 is connected withthe pump 30, and the supply-pipe 28 is secured to a portion of thewindmill-frame that turns in a horizontal plane, so as to move in unisontherewith, and the branch pipes 29 are then permanently connected withthe oil-holes of the windwill, and obviously the collar 13 ispermanently fixed to the tower, and the ring 24 will freely rotate withthe turn-table of the wind-wheel. Assuming that itis desired to oil theworking parts of the windmill and turn table, the operator first pressesthe lever 22 downwardly and secures it in position. This will press theedges of the ring 24 firmly into the Washer 27 and prevent oil fromleaking through between the ring and the collar. Then the operatormanipulates the pump 30, which is filled with oil, thereby forcing theoil through the pipe 34 into the annular chamber 26 and from the annularchamber 26 through the supply-pipes 28 and 29 to the oil-holes. When asufficient quantity of oil has been supplied to the work ing parts, thepump 30 is stopped and obviously all of the oil in the supply-pipes willreturn into the pump. After the oil returns the lever 22 is released,and the windmill is again ready for use and there is no oil remaining inquantities at the top of the windmill-tower, where it will be liable toleak or be affected by atmospheric conditions.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is-

1. Animproved windmill-oilingapparatus,

comprising in combination a collar to be pei manently fixed to the topof the windmilltower, a ring having an annular chamber therein rotatablymounted on top of the collar, a pipe leading from the annular chamber tothe ring to discharge into the oil-holes of the windmill, a pump at thebottom of the windmill-tower and a pipe leading from the pump to theannular chamber of the said ring, for the purposes stated.

2. An improvedwindmill-oiling apparatus, comprising in combination atwo-part collar to be applied to the opposite side of the top portion ofthe windmill tower, and to be bolted together and secured to thewindmilltower, a two-part ring having an annular chamber in its innersurface, the parts of which may be bolted together, means for holdingthe said ring in position on top of the collar, whereby it is heldagainst all but rotary movements, a supply-pipe connected with the ringleading from the annular chamher to points of discharge at the oil-holesof the windmill, a pump at the base of the windmill and a pipe leadingfrom the pump to the said annular chamber, for the purposes stated.

3. An improved windmill-oiling apparatus, comprising in combination atwo-part annular collar the parts of which may be bolted together andfirmly fixed to the top of the windmill-tower, a series of guides'fixedto the inner surface of the annular collar and projecting above it,slots in said guides, rollers mounted in the tops of said slots toproject over the annular collar, means for simultaneously directing theslots downwardly and holding them in position, a washer on top of theannular collar, a two-part annular ring and means of securing the partstogether, said ring having an annular chamber in its inner surface andalso having a flat top surface upon which the said rollers bear, asupply-pipe fixed to the annular ring and communicating with the annularchamber thereof and designed to communicate with the'oilholes of thewindmill, a pump to be fixed to the base of the windmill-tower and thesupply-pipe passed through the annular collar to discharge into theannular chamber, substantially as and for the purposes stated.
